' skilled in the art to which it appertains to make and use the same, reference being had t0 the accom anying drawins, forming part of this speccation, in whic Figure 1 is a sectional .viewof one form of my invention; Fig. 2 is fanend view thereof; Fig. 3 is a sectional view of a slightly modified form; Fig. 4 is a sectional view of still another form ;'Fig. 5 is an enlarged .detail erspeotive view ofthe spacing ring; and ig. 6 is a view showing my im roved bearin applied to the crank shaft o an engine. h1s invention relates to ball bearings.

One object of my invention is to provide a ball bearing of the annular type comprising a plurality of circles of balls and ball races therefor, part of 'the ball races being comosed of a plurality of cones and an interme- 'ate s acm member.

Anot er o ject of my invention is to rovide a ball bearing which is constructe to resist excessive lateral strains or end thrusts.

Referring to Fig. 1 of the drawings, 1 designates a ring thatforms the' outer member of the bearing, said ring beineP provided on its inner side with ball races or two circular lrows of balls 2 and 3. The inner member of the bearing is formed by two cones 4 and 5 arranged as shown in Fig. 1 so that their bearinfy faces taper in opposite directions,

each 0I said cones forming the inner race for one row of balls. Interposed between these cones to hold them-spaced apart and at the proper distance from their cooperating ball races formed on the outer rinf1r 1, is a s acing member or filler-consisting of, a rin ormed from'a number of sections 6a.' 'I orm the inner member of the bearing in this manner so that I can insert both rows of balls inside of the outer ring 1, which is recessed or ooved, as hereinafter described, 'the balls eing placed in position by iirst inserti the balls of row 3 and adjusting the cone lwghich formsthe inner race forl said row in proper position with relation to the cooperating race 1nthe outer rin lthen inserting the balls of the other row 2 etween the outer race therethen passe for in the rin 1 and the cooperating cone 4, said cone at t 's time being arrangedJ close to the cone 5 so as to provide a suflicient space between the race members for the second row 2to permit the balls of this row to be 1nserted. After the balls of the second row have been inserted, the/cone 4 for this row is moved away from the cone 5 into proper position with relation to the outer race for the second row, and the sections 6a of the s acing ring are then put in place to hold sai cones in their ad'usted position. The shaft 6 is through the spacing ring and through the cones to hold said ring in position and the sections 6a of the spacing ring are prevented from radial movement by means of flanges 6 formed thereon which are seated in an annular groove formed on the inner end face of the cone 4. When the race members wear away after the bearing-has been in use for some time I remove the spacing rin and insertl another spacing ring of greater t' ckness or I can use the original spacing ring andthe bearing faces 7 resist excessive lateral strains or end thrusts.

Each of the cones which form the inner ball races are one-point bearings, thepoint of tangency being thesame distance from either of the two correspondingpoints of tangency on the outer ring 1.

If desired, the bearing can be formed as shown in Fig'. 3, the outer member being composed of two cones 4a and 5a and an intermediate spacing ring of substantially the same construction as shown in Fig. 1, and the inner member of the bearing being formed by a ring 1a having ball races formed on its-outer surface, each of said races comprising a bearing face 8 that offers resistance at right angles to the axis of rotation and a bearing face 7al that resists end thrusts. In the form shown in Fig. 3 the iiange on the sectional spacing ring'will be formed at the outer edge of said ring to prenecting rod', the innermember of the bearf vent the sections from moving inwardly, t 'connect them together. The' outer 6.5

the ring being retained in position by the member 10 in which the bearing is mounted. If desired, the bearing can be provided with several circular rows of balls, as shownin Fig. 4, which illustrates a bearing provided with five rows., In this form 'the outer member of the bearing is composed of a sleeve provided on its interior with end thrust resistingfaces 7b, the inner surface 8 1j of the sleeve between these faces 7 b constituting the bearing faces that offer reslstance at right angles to the aXis of rotation. The inner member of the bearing is composed' of a cone 4b and a cone 5b having a tubular extensionll provided on its outer face w1th three grooves that constitute the inner races for the three intermediate rows .of balls, a spacing ring 6b being arranged between the cone 4b and the'inner end of the tubular extension on the cone 5b. To permit the intermediate rows of balls to be serted the outer member is provided on its inner surface adjacent one end with a pocket 12, as shown in Fig. 4, the intermediate rows being first inserted and then the .end rows being insertedl as previously described in connection with the form shown in Fig. 1. It will, of course, be obvious'that the members of the form shown in Fig. 4 could be transposed in the same manner as shown Fig. l'

K My improved bearing can be used 'advantageously as a bearing for the crank shaft of an engine and is a decided improvement upon the bearings which have heretofore been used for this'purpose in view of the fact that its dimensions. are much less than those of said bearings. My bearing can also be usedV for a crank shaft connecting rod andso far as I know, itis the rstfbearing that has been found to be ,practicable for this purpose. In Fig. 6 I -have illustrated my invention used as oneof the bearings for a crank shaft and also as 'abearing for a crank shaft coning being com osed of the crank shaft 15 havingincline faces 16 turned thereon to vform portions of the inner ball races. The outer member of the bearing is composed of two cones 17 and-a spacing ring 18 of substantially the same construction as shownv In the ball bearings that have heretofore been used for crank shafts, the inner member ofthe bearing had to be. made large enough so that it. could be slipped over the` cranks of the shaft and consequently said inner member was of much greater diameter than the portion of the shaft it encircled when in o erative position, wedges or other suitable evices lbeing interposed between the shaft and the inner member of the bearand the races in the coperatin ber .so that the result was lan unsightly bearing of great diameter. AIn fact, the

:diameter of the bearing was so great that it was not practicable to use it as a bearing for the connecting rod so that the connecting .rod was not provided with a ball bearing at the point Where 'itencircled the crank.v My bearing overcomes these objectionable features and enables a connecting rod to be provided with a ball bearing at the point where it encircles lthe crank, thev inner member of the bearingbeing formed by the portion 19 of the crank which the-connecting rod 20 encircles.
